6 Factors That Affect Mould Removal Cost
Area Affected
The single biggest cost driver. A small patch in one bathroom costs far less than mould throughout multiple rooms. Specialists typically quote per room or per square metre of affected area.
Mould Type
Toxic black mould (Stachybotrys) requires more extensive containment, PPE, and decontamination protocols than common surface moulds. Laboratory testing ($300-$800) may be needed to identify the species.
Location & Access
Mould on open surfaces is cheaper to remediate than mould inside wall cavities, roof spaces, or subfloors. Confined spaces require additional equipment and safety measures, increasing costs.
Severity & Depth
Surface mould on tiles can be cleaned, but mould that has penetrated into plasterboard, timber, or insulation requires removal and replacement of affected materials, significantly increasing cost.
Cause Treatment
If the moisture source (leak, rising damp, poor ventilation) also needs fixing, this adds to the total project cost. Some specialists offer package pricing for remediation plus cause treatment.
Containment Requirements
Larger jobs require negative air pressure containment to prevent spore spread during remediation. This adds setup time and equipment costs but is essential for protecting the rest of the home.
How to Save on Mould Removal Costs
Act Early
Early-stage mould costs a fraction of established growth to remove. A $500 job today could be a $3,000 job in three months. Don't wait.

Fix the Cause
Removing mould without fixing the moisture source means it returns. Spending more upfront on cause treatment saves money long-term.
